CVE-2022-22333

Service disruption via oversized Jetty GUI requests

Published Feb 23, 2022 · Updated Sep 16, 2024

Buffer overflow in IBM Sterling Secure Proxy 3.4.3.2, 6.0.2.0, and 6.0.3.0 allows attackers to disrupt service via crafted HTTP requests. The Jetty-based GUI in the Secure Zone fails to validate submitted form-content and HTTP-header sizes, allowing oversized input to overflow a buffer. Reachability requires network position inside the Secure Zone; exploitation interrupts availability without reported data disclosure or modification.
